QO TWO NEW WORLDS 



to assume that in both worlds there is the same 

 limit of speed, and hence also the same ether. 



I now propose to proceed in the opposite direction 

 along the scale of magnitude, and to investigate the 

 conditions met with when, instead of dividing all 

 sizes by 10,000 trillion, we enlarge them in that 

 proportion. I shall endeavour to show that we then 

 arrive at another world comparable with our own, 

 which I propose to call the supra-world. 



A dried currant has a roughly elliptical shape, its 

 dimensions varying from 0'3 cm. to 1 cm. Now en- 

 large this by the " world-ratio " 10 22 . It will then 

 become a body filling up the whole visible universe 

 out to the uttermost star visible in the most power- 

 ful telescope, or recorded by the longest photographic 

 exposure. Its 20,000 trillion atoms, if shining with 

 " infra-light," will, seen from within, become a 

 splendid starry vault, emitting the blaze of a bright 

 noonday, the stars being much more densely crowded 

 than those of the Milky Way. 



What changes will this starry world undergo in 

 a second of time? Obviously, the revolutions of 

 the stars which were once atoms will be much slower 

 than heretofore, and, however fast the motions of the 

 atoms or stars may be, they will be less effective 

 in producing a given change of configuration in 

 the proportion familiar to us from the infra-world 

 viz., 10 22 . Whatever changes a currant undergoes 

 in a second of our time will now be spread over a
